react-native - 错误命令失败：gradlew.bat app:installDebug

问题描述

当我运行“react-native run-android”或“npx react-native run-android”或“cd andriod ./gradlew clean”这些命令时，错误会显示

PS D:\work\Myproject-app> npx react-native run-android

我也尝试使用最新版本的 Gradle！

操作系统 Windows 10 节点：14.2.0 Java：java 版本“1.8.0_251” Java(TM) SE 运行时环境（内部版本 1.8.0_251-b08） Java HotSpot(TM) 64 位服务器 VM（内部版本 25.251-b08，混合模式） ) Gradle 版本：5.1.1

JAVA_HOME、ANDROID_HOME 和添加到环境的路径

解决方案

我没有足够的代表发表评论，但是....

我今天遇到了这个问题。我的情况是该项目在 Mac 上运行良好。但是，我需要让它在 Windows 系统上运行。在我的 android\app\build.gradle 文件中，我设置了一个 getPassword 方法，它可以让我轻松签署我的 apk。在 getPassword 方法中，我有这个调用：

commandLine 'security', '-q', 'find-generic-password', '-a', currentUser, '-s', keyChain, '-w'

我注释掉了对 getPassword 方法的所有引用，它开始工作没有问题。

问题的根源在于 mac 使用的“安全”命令行工具在 Windows 上不可用。由于我现在还需要使用 Windows 框，因此我已经在外部凭据文件中配置了密码。
